474 COLEOPTERA. 
Underside nigro-aeneous, finely sculptured, with elongate pubescence. 
Fourth abdominal segment nearly semicircularly emarginate, 5th twice as 
long, almost obconical, with a small subapical fovea, 6th narrow and e 
elongate. ¥ 
The remarkable, deeply sulcate pygidium by itself is sufficient for 
immediate separation from any of the preceding species. It is distinctly 
pubescent, rather smaller, much more nigrescent, but with more brightly 
coloured legs and shorter antennae than L. cheesemani (3150). The other 
near ally, L. obscurus (3151), can be at once distinguished by the incurved 
elytral base, prominent shoulders, dissimilar coloration, &c. 
Length, 3 mm.; breadth, 14mm. 
Queenstown, Lake Wakatipu. Half a dozen specimens, from Mr. M. O. 
Pasco and Mr. A. Philpott; January, 1914. 
3979. Luperus mediocris sp. nov. 
Nitid, bearing very few, inconspicuous, greyish hairs; aeneo-cyaneous, 
tibiae fusco-testaceous, femora and antennae fuscous. 
Head rather narrower than front of thorax, slightly rugose, with out- 
standing ashy hairs in front. Eyes large but not prominent. Thorax a 
third broader than long, the sides moderately marginate and very slightly 
curved, base a little oblique near the sides, with subrectangular angles ; 
dise without perceptible inequalities, irregularly, distantly, and very finely 
punctured. Elytra four times the length of thorax, a little broader than 
it is at the base, rather wider behind, with broadly rounded apices; dis- 
tinctly, moderately finely and closely punctate, slightly rugose, more finely 
near the almost unimpressed shoulders, and with a few minute interstitial 
punctures. Pygidium only slightly exposed. 
Antennae moderately slender, extending beyond middle thighs, 3rd 
joint evidently shorter than 4th, but longer than 2nd. Legs and tarsi 
moderate, tibiae straight. 
L. oleareae (2304), though larger and stouter, seems to be the most 
nearly allied species. Sharp’s L. aenescens (2316) has fusco-testaceous 
antennae and a long, narrow, horizontal pygidium. 
Length, 44.mm.; breadth, 2 mm. 
Unknown Land, west of Moa Basin. Four found by Mr. T. Hall in 
October, 1913.
